I would like to put a bid in for all of the components of this project. I have a BA(Hons) degree in English and creative writing so this is my specialty, but I am also a keen video editor.
I would also love to give the narration a try. I am English, so I hope my accent will suit the project. I think I would be more than capable of delivering the narration in whatever style is required.
In terms of music I am aware of websites that offer royalty/copyright free music for projects such as this, and if none is suitable I also have close friends who can have studied and can compose and record music fairly quickly and at no extra fee.
I have put 3 days as my initial estimate for the time it will take. This is just for the intial video. I suspect once I have completed one video and have got into the swing of things, I could work much more quickly.
